We look at the division of 86589355 by 376 
The aim is to understand the frequency of 376 in 86589355.

Advancing to step 1:
If we divide 8 by 376, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 376

Advancing to step 2:
86 divided by 376 is 0 with a remainder of 86.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 86 and we're left with 86.
Bring next digit (5) of the dividend behind the 86 and repeat the process: 865 / 376

Advancing to step 3:
865 divided by 376 is 2 with a remainder of 113.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 752 from 865 to get 113.
Grab the next digit (8) from the dividend, add it to 113, then carry on: 1138 / 376

Going ahead to step 4:
376 goes into 1138 3 times with a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 23.0
Subtracting 1128 from 1138 leaves us with 10.
Append the next digit (9) from the dividend to 10 and continue with: 109 / 376

On to step 5:
When dividing 109 by 376, we get 0 with a remainder of 109.
The number 0 becomes the next digit in our result. 
Result so far: 230.0
Subtracting 0 from 109 leaves us with 109.
Grab the next digit (3) from the dividend, add it to 109, then carry on: 1093 / 376

Advancing to step 6:
376 goes into 1093 2 times with a remainder of 341.
Record the quotient 2 as the next digit in the result. 
Result so far: 2302.0
If we subtract 752 from 1093, we get 341.
Grab the next digit (5) from the dividend, add it to 341, then carry on: 3415 / 376

On to step 7:
376 can be fit into 3415 9 times, resulting in a remainder of 31.
The number 9 becomes the next digit in our result. 
Result so far: 23029.0
The remainder is 31 after subtracting 3384 from 3415.
Fetch the next digit (5) from the dividend, attach it to 31 and continue: 315 / 376

Let's proceed to step 8:
376 goes into 315 0 times with a remainder of 315.
Write down 0 as next digit of the result. 
Result so far: 230290.0
Deduct 0 from 315 and we're left with 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

On to step 9:
376 goes into 3150 8 times with a remainder of 142.
The next digit of our result is 8. 
Result so far: 230290.8
Deduct 3008 from 3150 and we're left with 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

On to step 10:
376 goes into 1420 3 times with a remainder of 292.
Put 3 as the next digit of the answer. 
Result so far: 230290.83
Deduct 1128 from 1420 and we're left with 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

On to step 11:
The number 376 fits into 2920 7 times, leaving a remainder of 288.
The number 7 becomes the next digit in our result. 
Result so far: 230290.837
If we subtract 2632 from 2920, we get 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Let's proceed to step 12:
376 can be fit into 2880 7 times, resulting in a remainder of 248.
Use 7 as the next digit of our solution. 
Result so far: 230290.8377
Subtract 2632 from 2880 to get 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

The final outcome is 230290.8377, with a leftover of 0.00248.
